  • 2d06d8c49   [CPUFREQ] use dynamic debug instead of custom infrastructure ... Browse Code »

    With dynamic debug having gained the capability to report debug messages
    also during the boot process, it offers a far superior interface for
    debug messages than the custom cpufreq infrastructure. As a first step,
    remove the old cpufreq_debug_printk() function and replace it with a call
    to the generic pr_debug() function.

    How can dynamic debug be used on cpufreq? You need a kernel which has
    CONFIG_DYNAMIC_DEBUG enabled.

    To enabled debugging during runtime, mount debugfs and

    $ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control

    for debugging the complete "cpufreq" module. To achieve the same goal during
    boot, append

    ddebug_query="module cpufreq +p"

    as a boot parameter to the kernel of your choice.

    For more detailled instructions, please see
    Documentation/dynamic-debug-howto.txt

  • c4d14bc0b   [CPUFREQ] Don't export governors for default governor ... Browse Code »

    We don't need to export the governors for use as the default governor,
    because the default governor will be built-in anyway and we can access
    the symbol directly.

    This also fixes the following sparse warnings:

    drivers/cpufreq/cpufreq_conservative.c:578:25: warning: symbol 'cpufreq_gov_conservative' was not declared. Should it be static?
    drivers/cpufreq/cpufreq_ondemand.c:582:25: warning: symbol 'cpufreq_gov_ondemand' was not declared. Should it be static?
    drivers/cpufreq/cpufreq_performance.c:39:25: warning: symbol 'cpufreq_gov_performance' was not declared. Should it be static?
    drivers/cpufreq/cpufreq_powersave.c:38:25: warning: symbol 'cpufreq_gov_powersave' was not declared. Should it be static?
    drivers/cpufreq/cpufreq_userspace.c:190:25: warning: symbol 'cpufreq_gov_userspace' was not declared. Should it be static?

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
